本發明是有關一種噴嘴對撞融冰系統，特別是一種應用於動態融冰之噴嘴對撞融冰系統，能夠透過不同噴嘴排列方式，讓不同噴嘴噴出之水柱能夠產生對撞並擴散濺灑進行融冰，如此將能夠具有更高釋冷率以及更短的融冰時間。The invention relates to a nozzle collision ice melting system, in particular a nozzle collision ice melting system used for dynamic ice melting. Through different nozzle arrangements, water columns ejected from different nozzles can collide and spread and splash. Melting ice will result in a higher cooling rate and shorter ice melting time.
儲冰式空調為一種潛熱儲能裝置，主要利用相變化所需之潛熱來儲存能量，以傳統儲冰式空調來說，儲冰槽作為儲冰式空調的主要核心，儲冰槽融冰系統有分為內融冰與外融冰系統，目前主要採用內融冰儲冰槽，原因在於內融冰系統容易與一般空調設計結合且融冰過程中不易形成融冰死角，儲冰槽利用率較高，總體設備成本較低，從經濟考量與方便性來說皆有利於此系統。Ice storage air conditioners are a latent heat energy storage device that mainly uses the latent heat required for phase changes to store energy. For traditional ice storage air conditioners, the ice storage tank is the main core of the ice storage air conditioner. The ice storage tank ice melting system There are internal ice melting systems and external ice melting systems. At present, internal ice melting and ice storage tanks are mainly used. The reason is that the internal ice melting system is easy to integrate with the general air conditioning design and is not easy to form ice melting dead corners during the ice melting process. The utilization rate of the ice storage tank Higher, the overall equipment cost is lower, which is beneficial to this system in terms of economic considerations and convenience.
但內融冰儲冰槽之缺點也相對較明顯，即為短時間內無法釋放大量的冷能，供應室內負載所需，其原因在於內融冰的冰層包覆鹵水盤管，融冰時水層會沿著盤管的周圍生成，當水層越厚，熱阻也會隨之增加，導致融冰速度變慢，不利於快速釋放冷能。However, the shortcomings of the internal melting ice storage tank are also relatively obvious, that is, it cannot release a large amount of cold energy in a short period of time to supply the indoor load. The reason is that the ice layer of the internal melting ice covers the brine coil. A water layer will form around the coil. When the water layer becomes thicker, the thermal resistance will also increase, causing the ice melting speed to slow down, which is not conducive to the rapid release of cold energy.
而一般業界大多是搭配管體開孔來輔助融冰，但由開孔流出的水所能夠融冰範圍是非常侷限的，故融冰時間仍然很長，且平均釋冷率也不夠高，如此亦不利於快速釋放冷能。In general, most of the industry uses openings in the pipe body to assist in melting ice. However, the ice-melting range of the water flowing out of the openings is very limited, so the ice-melting time is still very long, and the average cooling rate is not high enough. It is also not conducive to rapid release of cold energy.
因此，本案使用多個噴嘴裝置，而不同噴嘴裝置係相對排列設置，並使至少兩個噴嘴裝置之開口的噴灑角度係有交錯，而不同噴嘴裝置之開口所噴出之水柱能夠產生對撞並擴散濺灑於該內融冰儲冰槽之液面處，以對該液面處進行融冰，如此將能夠減少融冰時間，並提高平均釋冷率，因此，本案應為一最佳解決方案。Therefore, this case uses multiple nozzle devices, and the different nozzle devices are arranged oppositely, so that the spray angles of the openings of at least two nozzle devices are staggered, and the water columns sprayed from the openings of different nozzle devices can collide and spread Splash on the liquid surface of the internal ice melting storage tank to melt the ice on the liquid surface. This will reduce the ice melting time and increase the average cooling rate. Therefore, this case should be the best solution. .

As shown in Figure 1A, the nozzle device 31 has a The opening 311 is inclined downward, and the top of the nozzle device 31 has a water inlet 312, and the ice water entering through the water inlet 312 can be sprayed out from the opening 311.
如第1B圖所示，該噴嘴裝置31之開口311的傾斜角度θ為5~15度。As shown in Figure 1B, the inclination angle θ of the opening 311 of the nozzle device 31 is 5 to 15 degrees.
如第1B圖所示，該噴嘴裝置31之開口311的高度h為1~5mm。As shown in Figure 1B, the height h of the opening 311 of the nozzle device 31 is 1~5 mm.
如第1C圖所示，該噴嘴裝置31之開口311的噴灑角度α為45~75度。As shown in Figure 1C, the spray angle α of the opening 311 of the nozzle device 31 is 45 to 75 degrees.
如第2圖所示，噴嘴對撞融冰系統係包含有內融冰儲冰槽1、金屬盤管2、對撞噴灑組3及抽水管路4，其中該內融冰儲冰槽1內部係儲存有冰水13，而該金屬盤管2係設置於該內融冰儲冰槽1內部，該金屬盤管2係與一鹵水管路（圖中未示）相連接，該鹵水管路用以將一低溫鹵水送入該金屬盤管2，並因低溫使該金屬盤管2表面係凝結有一冰層，而當融冰一定程度後，該內融冰儲冰槽1之液面處11會形成浮冰12。As shown in Figure 2, the nozzle collision ice melting system includes an internal ice melting and ice storage tank 1, a metal coil 2, a collision spray group 3 and a water pumping pipeline 4. The interior of the internal ice melting and ice storage tank 1 Ice water 13 is stored, and the metal coil 2 is installed inside the inner melting ice storage tank 1. The metal coil 2 is connected to a brine pipeline (not shown in the figure), and the brine pipeline It is used to send a low-temperature brine into the metal coil 2, and due to the low temperature, an ice layer condenses on the surface of the metal coil 2. When the ice melts to a certain extent, the liquid level of the internal ice-melting ice storage tank 1 is 11 will form ice floes12.
本案的低溫鹵水係透過一鹵水機（圖中未示）將鹵水進行降溫形成一低溫鹵水，鹵水通過內融冰儲冰槽1之金屬盤管2進行儲冷，使內融冰儲冰槽1內的冰水13結冰形成冰塊，鹵水再經由金屬盤管2被傳送回鹵水機重新開始循環工作。The low-temperature brine in this case is cooled by a brine machine (not shown in the figure) to form a low-temperature brine. The brine is stored cold through the metal coil 2 of the internal melting ice storage tank 1, so that the internal melting ice storage tank 1 The ice water 13 inside freezes to form ice cubes, and the brine is sent back to the brine machine through the metal coil 2 to restart the cycle.
而當鹵水經由鹵水管路被輸送至內融冰儲冰槽1，鹵水通過內融冰儲冰槽1內的金屬盤管2進行內融冰，使內部冰塊與鹵水進行熱交換輸出低溫鹵水，鹵水再經由鹵水管路被傳送至板式熱交換器與空調設備的冰水進行熱交換，最後鹵水經由鹵水管路被傳送回內融冰儲冰槽1重新開始循環工作。When the brine is transported to the inner melting ice storage tank 1 through the brine pipeline, the brine melts the ice internally through the metal coil 2 in the inner melting ice storage tank 1, so that the internal ice cubes and the brine exchange heat to output low-temperature brine. , the brine is then sent to the plate heat exchanger via the brine pipeline to exchange heat with the ice water of the air conditioning equipment, and finally the brine is sent back to the internal ice melting and ice storage tank 1 via the brine pipeline to restart the cycle.
該內融冰儲冰槽1底部的冰水13經由抽水管路4被傳輸至對撞噴灑組3，並由對撞噴灑組3使水柱3111進行對撞，以使澆淋至浮冰12的水分散的更加均勻，而冰水向下流經金屬盤管2，再由底部集水進入抽水管路4進入口而形成內循環擾流(動態循環攪拌)。The ice water 13 at the bottom of the internal melting ice storage tank 1 is transported to the collision spray group 3 through the water pumping pipe 4, and the collision spray group 3 causes the water column 3111 to collide, so that the ice water 13 is poured onto the ice floe 12 The water is dispersed more evenly, and the ice water flows downward through the metal coil 2, and then collects water from the bottom into the entrance of the pumping pipe 4 to form an internal circulation disturbance (dynamic circulation stirring).

每一個噴嘴裝置31所連接之抽水管路4皆會連接有一流量感測器7，用以能夠監測冰水13流量的狀態，其中流量感測器7之監測數據能夠傳送至一控制裝置(圖中未示)，以由該控制裝置控制該抽水馬達5，以維持所有噴嘴裝置31具有相同流量。 The water pumping pipeline 4 connected to each nozzle device 31 will be connected to a flow sensor 7 to monitor the flow status of the ice water 13. The monitoring data of the flow sensor 7 can be transmitted to a control device (Fig. (not shown), so that the control device controls the water pumping motor 5 to maintain the same flow rate of all nozzle devices 31.
該內融冰儲冰槽1內部更能夠設置有一液位感測器(圖中未示)，藉由液面高度之變化，偵測內融冰儲冰槽1之冰量多寡，並依照室內負載需求，得以透過調降抽水馬達5之抽取量，以降低融冰速率，反之，若是要讓融冰速率加快，則能夠提高抽水馬達5之抽取量，以提高融冰速率。 The interior of the internal ice melting and ice storage tank 1 can further be provided with a liquid level sensor (not shown in the figure), which detects the amount of ice in the internal ice melting and ice storage tank 1 through changes in liquid level, and adjusts the amount of ice in the internal ice melting and ice storage tank 1 according to the indoor temperature. The load demand can be reduced by reducing the pumping amount of the pumping motor 5 to reduce the ice melting rate. On the contrary, if the ice melting rate is to be accelerated, the pumping amount of the pumping motor 5 can be increased to increase the ice melting rate.
本案能夠與空調設備(例如空調箱、送風機、冷藏設備等之其中一種或其組合)進行連接，而連接與實施方式係為習用技術，故不重複贅述。 This case can be connected to air-conditioning equipment (such as one or a combination of air-conditioning boxes, blowers, refrigeration equipment, etc.), and the connection and implementation methods are common techniques, so the details will not be repeated.
如第3A圖所示，係為本案對於噴嘴裝置31的排列樣態(平行排列)，該對撞噴灑組3之每兩個噴嘴裝置31之開口朝向能夠相對應，使每兩個噴嘴裝置31進行平行排列。 As shown in Figure 3A, it is the arrangement of the nozzle devices 31 in this case (parallel arrangement).

如第4圖所示，是一般動態融冰系統之整體配置示意圖（一般管路實施樣態），其中是使用管路8橫置於該內融冰儲冰槽1之液面處11上方，而該管路8有開設多個開孔81，該抽水馬達5能夠抽取該內融冰儲冰槽1內部之冰水13，並透過該抽水管路4將該冰水13運送至該管路8，而管路8之開孔81所流出之水流用以對該液面處11的浮冰12進行融冰。As shown in Figure 4, it is a schematic diagram of the overall configuration of a general dynamic ice melting system (general pipeline implementation), in which the pipeline 8 is placed horizontally above the liquid level 11 of the inner ice melting storage tank 1. The pipeline 8 has a plurality of openings 81, and the water pumping motor 5 can extract the ice water 13 inside the internal ice melting and ice storage tank 1, and transport the ice water 13 to the pipeline through the water pumping pipeline 4. 8, and the water flowing out of the opening 81 of the pipeline 8 is used to melt the ice floe 12 at the liquid surface 11.
本案係以釋冷率進行比較不同實施樣態與一般管路實施樣態的差異，而釋冷率公式說明如下，其中將儲冰槽視為一控制體積，由此系統內的能量平衡方程式，可得到儲冰槽之釋冷率： = (1) 其中 為槽內水之質量；H為槽內水之比焓； 為鹵水和槽內水之熱傳率； 為外界傳至儲冰槽內之熱傳率。本案儲冰槽進行儲冰後，其環境熱損失與釋冷量相比微小，因此忽略其熱損耗，及 ≅ 0。因此儲冰槽之釋冷率等於高溫鹵水所帶走之熱量，將槽內之金屬盤管視為一控制體積，可得到融冰時高溫鹵水之熱傳率： (2) 將(2)式對時間t進行積分，可得出儲冰槽開始進行融冰至時間t之累積釋冷量： (3) 將(2)式進行平均，可得儲冰槽之釋冷率： (4) This case uses the cooling rate to compare the differences between different implementations and general pipeline implementations. The cooling rate formula is explained as follows. The ice storage tank is regarded as a control volume. Therefore, the energy balance equation in the system is, The cooling rate of the ice storage tank can be obtained: = (1) Among them is the mass of water in the tank; H is the specific enthalpy of water in the tank; is the heat transfer rate of brine and water in the tank; It is the heat transfer rate from the outside to the ice storage tank. After the ice storage tank in this case stores ice, its environmental heat loss is small compared with the cooling capacity, so its heat loss is ignored, and ≅0. Therefore, the cooling rate of the ice storage tank is equal to the heat taken away by the high-temperature brine. Considering the metal coil in the tank as a control volume, the heat transfer rate of the high-temperature brine during ice melting can be obtained: (2) By integrating equation (2) over time t, we can get the cumulative cooling capacity from when the ice storage tank begins to melt ice to time t: (3) By averaging equation (2), the cooling rate of the ice storage tank can be obtained: (4)

As shown in the figure, the three implementation patterns of this case (parallel arrangement, The average cooling rate of centerline arrangement and staggered arrangement is better than that of ordinary pipeline openings. In the implementation of this case, since the staggered arrangement can spread the splash the most, the average cooling rate performance is also the same. most.

本發明所提供之噴嘴對撞融冰系統，與其他習用技術相互比較時，其優點如下： 1. 本案使用多個噴嘴裝置，而不同噴嘴裝置係相對排列設置，並使至少兩個噴嘴裝置之開口的噴灑角度係有交錯，而不同噴嘴裝置之開口所噴出之水柱能夠產生對撞並擴散濺灑於該內融冰儲冰槽之液面處，以對該液面處進行融冰，如此將能夠減少融冰時間，並提高平均釋冷率。 2. 本案之噴嘴以交錯排列方式有最高平均釋冷率為以及最短的融冰時間，中心線排列次之，最後是平行排列，三者相較於一般管路開孔，有更高釋冷率以及更短的融冰時間。 When compared with other conventional technologies, the nozzle collision ice melting system provided by the present invention has the following advantages: 1. This case uses multiple nozzle devices, and the different nozzle devices are arranged opposite each other, so that the spray angles of the openings of at least two nozzle devices are staggered, and the water columns sprayed from the openings of different nozzle devices can collide and spread. Splash on the liquid surface of the internal ice-melting ice storage tank to melt ice on the liquid surface. This will reduce the ice-melting time and increase the average cooling rate. 2. The nozzles in this case are arranged in a staggered manner to have the highest average cooling rate and the shortest melting time, followed by the centerline arrangement, and finally the parallel arrangement. Compared with ordinary pipeline openings, the three have higher cooling rate and shorter ice melting time.
